WRENCH AND ROD-VISE.

SPECIFICATION forming part of Letters Patent No..501,177, dated July 11, 1893.

Application filed November 14, 1892. Serial No. 451,980. (No model.)

To all whom it may concern.- 7

Be it known that I, JOHN W. WULIF, acitizen of the United States, residing in Blair, in the county of Washington and State'of Nebraska, have invented a new and useful Oombined Wrench and Rod-Vise, of which the following is a specification.

My invention relates to and has forits principal object the provision of a wrench and vise combined for making the coupling in the pump rods of iron pumps, also, to provide a simple and convenient tool for turning, or holding other round rods or bolts. I attain these objects by the mechanism illustrated in the accompanying drawings in which Figure 1 is a perspective'view of my contrivance. Fig. 2 is an enlarged detail view of the end of the set screw 6; and Fig. 3 shows the application of my contrivance in coupling a pump-rod.

Similar numerals refer to similar parts throughout the several views.

A fiat oval-shaped head 1 with an integral handle 10, I have chosen .as the most desirable form for the principal part of my contrivance; a notch or indenture 7, is out in one edge of the head forming the jaws 2 and 3 which are adapted to engage any polygonal nut or coupling that it would fit. Asteel set screw 6 having arectangular head 4. adapted to be turned with a wrench, is threaded through the jaw 2 so that the end of the screw 6 enters, one notch near the bottom, the axis of the screw beinginclined toward the curved bottom of the notch; the mouth of the notch inclined toward the head of the screw; the head of the screw has the perforation 5 by means of which it may be turned with a punch or rod; the face of the forward end or point of the screw 6' is formed with V shaped annular ridges 9 and 9, concentric with the screw, indicated in section at 8, in Fig. 2.

In Fig. 3, 13 represents the upper end of a section of pump-pipe, 12 the rod that connects the pump handle with the plunger, and 11 a joint or coupling in the rod.

In force pumps having a stuffing or packing box at the top, it is often necessary that the joint in the rod shall be a little below the joint in the pipe when all is set for use, (the section of the pipe and rod always correspondnotch 7 until it rests in the bottom. The set screw is then turned in, forcing the rod firmly into the bottom of the notch preventing it from slipping out; the V shaped annular ridges cut into the rod and prevent it from turning or slipping endwise; right or left hand threads may be out on the rod and it may be coupled or uncoupled without becoming released from the wrench-vise; in mending broken rods itoften saves removing the whole or part of the pipes and rod from the well. Nearly if not all the pipe wrenches in use, will hold only against a turn in one direction, unless reversed on the rod, and even then there is danger of the rod being released and slipping down in the pipe, causinga loss of labor and time; it will be observed that the above objections are overcome by my contrivance.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a combined wrench and rod-vise, a head consisting of a pair of oppositely disposed integral jaws, with a suitable handle,- in combination with aset screw having on its point end concentric annular, V shaped ridges,

and so threaded through one of thejaws that the point bears toward the bottom of the space between the jaws,substantially as shown and described.

2. In a combined wrench and rod-vise the combination of the head 1 having the integral jaws 2 and 3 and the handle 10 with the set-screw 6 having the head 4, and perforation 5, the point 6 provided with the concentric annular V shaped ridges 9 and 9, the set screw so placed in the head that its point bears toward the bottom of the opening between the jaws substantially as shown and described.

Signed at Blair, in the county of Washington and State of Nebraska, this 9th day of November, 1892.

JOHN W. WULFF.

In presence of J. E. KETCHMARK, J. F. BUROHAM.
